Ability to upgrade to packs from multiple modules

[AndyMac]

For people who have purchased a number of modules from a pack, and then decide they want to get the pack (or larger pack) it would be excellent if the store provided a way to "upgrade". In my case, I had purchased VCF-20 when it first came out, then VCO-20 when that was released. Now with the ESP-20 being released, it would be brilliant if there were an upgrade from the VCF-20 + VCO-20 to the MS Vintage Pack, so that any future new modules would then be included - rather than being pretty much locked into buying these individually. I have seem similar questions around the PSP packs, and have also wondered about it for the packs that I develop.

This would be an awesome addition to the store's capabilities if it can be made possible.
